Pages broken on website

My home page, contact page and blog page on my website seems to be broken. All my other pages are working fine. I have been in contact with my hosting provider who have informed me that on their end the pages seem to be working fine. I have however checked on three different computers and all seem to be broken.

The broken pages also seem to be showing an old version of the website with an old theme. I have cleared the cache on my web browser, on the backend of the site and also the server both with my hosting provider and cloudflare. I have tried to disable all plugins to see if a plugin is the problem. Nothing has worked so far.

The only changes that I have recently made to the site was a change of theme from Soledad to Astra. I’m not sure whether this might be the cause. I have tried activating different themes on the site to see if that fixes it but it hasn’t.

Hope someone can help.
